Polish documentation formatting and standardise structure

[admdly]

Summary by cubic

Polished docs formatting, navigation, and examples for clearer guides, and moved GitHub Actions to ubuntu-slim for leaner CI.

• Refactors

  • Adopted {% steps %} and {% filetree %} blocks across docs for consistent, scannable instructions.
  • Normalized code fences (text, twig) and cleaned up Twig examples (removed escape characters with clear “remove backslashes” notes).
  • Fixed internal links and anchors (added trailing slashes, corrected section anchors, updated paths and NGINX links).
  • Centralized the “breaking changes” caution into a reusable partial and applied it across development guides.
  • Improved tables and examples (e.g., ISO 8601 timestamps, corrected Twig API usage in theme docs), and set sidebar ordering for product-type pages.
  • Updated README with clearer redirect guidance and trimmed outdated sections; removed the outdated contributor code of conduct page.
  • Fixed manifest.json indentation in file tree examples.

• CI

  • Updated ci and dependency-review workflows to run on ubuntu-slim.
